The steering rack is an integral part of any modern car, including Renault Logan. It is included in the design of the steering mechanism and ensures the transfer of force from the steering wheel to the swivel rod of each wheel. If a malfunction is suspected and adjustment is not possible, the steering rack should be replaced as soon as possible. The procedure does not cause difficulties and can be done by hand with a repair kit and knowledge of the repair rules.
On Renault Logan, depending on the release, steering racks of various types were installed - mechanical and hydraulic.
Cars of the first generation - phase 1 (2004, 2005, 2006, 2007,2008, 2009 of release) with a 1.4 engine in two proposed trim levels were equipped with a mechanical steering rack, and a car with a 1.6 liter engine was equipped with a hydraulic steering rack. Restyling models (2009, 2010, 2011, 2012, 2013, 2014, 2015 onwards) and second generation versions (2014, 2015, 2016, 2017) in the simplest trim levels are offered without power steering (hydraulic booster), which is ordered separately .
According to the manufacturer's instructions, the service life of the steering rack without any complaints about quality is 180-200 thousand kilometers, subject to regular preventive inspection.
The main reasons for the failure of the node and the appearance of malfunctions include:
Diagnosis of a malfunction is detected by a simple inspection and attentive attitude to the behavior of the car on the road. The following signs will tell you about an upcoming repair:
Sometimes the situation can be corrected if the part is adjusted, but this is not always possible. Often, adjusting the steering rack does not fix the problem, and then it is necessary to make a replacement: remove the old element and install a new device.
The weak link of the steering rack are bearings and thrust bushings, which most often cause inefficient operation.
The block diagram of the steering is shown in the figure.
It is not difficult to independently perform work on troubleshooting the steering rack, the main thing is to determine the cause of the breakdown. On the network you can find a lot of photos and videos that tell in detail how to replace one or another element of the device.
Before installing a new homemade bushing, you need to sharpen it by correcting the size. Before you put the part, you should lubricate the seat. Assembly is carried out in the reverse order.
To troubleshoot, another method is also used - you need to tighten the adjusting plug.
The problem of steering wheel knock is solved by adjusting the distance between the rack and gear. In this case, it is enough to tighten the steering rack as much as possible, and the problem may disappear.
Adjustment features differ depending on the presence or absence of power steering.
Situations where, with the engine turned off, turning the steering wheel causes a knock in the steering rack, according to the manufacturer's instructions, do not require adjustment, although the mechanism contains a special nut. After starting the engine, you should wait 10-20 seconds, and the noises most often go away. Auto service specialists claim that this is an indicator of the normal operation of the power steering, and no intervention is required. If the problem persists, then before adjusting, the tin washer (heat shield) should be bent. This will save the car from the end of the warranty service. The washer fits snugly on the crankcase bolts. Sometimes it may just be necessary to change the oil in the power steering.
In this case, you will need a 10 hexagon. Work algorithm:
Repair and installation of a new steering rack is not the most difficult process if you follow it strictly according to the instructions. Marriage in work will lead to additional problems in management. When buying a new part, do not forget about replacing consumables, choosing the right name and article for each.
For more than ten years, Renault Logan has been successfully operated on Russian roads. High reliability, maintainability and cost have won the attention of a huge number of motorists. During all this time, Logan owners have accumulated considerable experience in the maintenance and repair of various parts and mechanisms of this car. This also applies to the steering, namely the steering rack, because symptoms in the form of knocks and crunches on cars of different years, appear periodically.

Front hub bearings and support bushings, according to statistical studies, are one of the weak points in the Renault Logan chassis.
These malfunctions during movement are determined by the following signs:
Some masters in car services, servicing such a malfunction, are limited to tensioning the adjusting plug. However, the manufacturer categorically does not support such repair methods and prohibits them. Explaining this by the fact that the gear-screw (worm) transmission, with excessive tightening torque, begins to wear out the teeth on the gear intensively, which in turn leads to even greater malfunctions.
But what then to do in such a situation? You say! Because with obvious problems, a complete replacement of the steering rack is indispensable, and the price in today's economic situation bites a lot.
The price for a new steering rack for Renault Logan "bites" a lot
In such a situation, experienced owners of Renault Logan offer to carry out such repairs on their own with their own hands. Stipulating that everyone should rely either on their own strength or what is best repaired under the supervision of a knowledgeable craftsman.
The table below shows the most common breakdowns on the Renault Logan steering rack and how to solve them:
In this article, we will consider the Renault Logan steering unit. Many Logan owners are interested in the Logan steering rack purchase and replacement price. But perhaps you only need to adjust or repair the Logan steering rack without gur or with gur. You can learn how to diagnose and repair steering Logan from this article, as well as by contacting our car service with this question.
The steering rack of a car, including the Logan steering rack, is a reliable, durable unit that rarely deforms and breaks. But constant loads (steering wheel torsion) can disable the part, which leads to the need to repair the Renault Logan steering rack, or the Logan steering rack needs to be replaced. The process of restoring the steering component in most cases turns out to be pointless, so many are interested in the Renault Logan steering rack purchase and replacement price.
And although the Renault Logan steering rack with gur is one of Logan's weakest points (if the Logan steering rack is without gur, then it will last longer and more reliable, because the design is less complicated), but do not rush to buy a Logan rack right away. The craftsmen working in our car service have extensive experience in dealing with the problems presented, and perhaps Logan steering column repair will help you, or you only need to replace the Renault Logan steering rack boot or oil seal.
In any case, we recommend that you first diagnose the Renault steering rack in a car service to save time and money.
Let's take a look at the components:
Tie rods and tips responsible for turning the wheels are attached to the sliding mechanisms of the part.
The toothed bar with gears is responsible for the transfer of force from the steering wheel to the traction, controls the wheelset.
The body (crankcase) is a component made of aluminum, inside it contains all the main rack mechanisms.
The spring system ensures a snug fit of the rack to the gears, and also saves the steering wheel from free walking, backlash.
Limiters regulate the maximum value of steering wheel turns to the left and right sides.
Bearings - used for ease of manipulation carried out when turning the rail.
Despite the high strength of the mechanism, it is often subjected to accidental deformations, which in the end can completely disable the part, and in this case, the Renault Logan steering rack will need to be replaced.
Here are a few main symptoms that indicate a malfunction of the Renault steering assembly - one of the most important parts of the car:
A characteristic knock when making manipulations with the steering wheel.
The steering wheel becomes stiff, or turns only in one direction.
An incomprehensible hum in the hydraulic booster is also a signal that it is time to diagnose the rail.
After long periods of parking on the asphalt, large oil stains remain under the car, symbolizing the leakage of the component mechanism.
There are several main factors that negatively affect the integrity and performance of the steering assembly as a whole:
Accidentally hitting potholes, hitting curbs or serious bumps, traveling on uneven, dusty roads - all this can disable a part in a matter of months.
Cold: Many drivers who use the car in winter forget to turn the steering wheel to the left and right several times before starting to move. This procedure is necessary for the rapid heating of the GU fluid, which has a certain operating temperature.
Untimely replacement of the aforementioned fluid also becomes a frequent breakdown problem.
Negligent attitude to periodic inspections and diagnostics of the steering unit can leave small cracks and leaks unnoticed. The neglected state of rack deformations can lead to a complete malfunction of the part, and therefore it will be necessary to replace the Logan steering rack without gur or with gur.
A general inspection of the steering assembly is carried out as follows:
The work is done in pairs. The master examines the bottom of the car, asking his partner to gently rotate the steering wheel in different directions. Thus, a certain position of the steering wheel is found out, at which a knock is noticeable.
When leaks occur, the anther is inspected.
Diagnostics in the service station can take place with a complete analysis of the steering assembly. In some cases, the Renault Logan steering column is being repaired, in other cases, for example, the replacement of the Renault Logan steering rack is required. It depends on the nature of wear and neglect of the steering assembly.
Because of this, experts often advise drivers to listen to their car, since any extraneous sound is a signal that certain parts are out of order, broken, or detached from the right place.
Adjusting the Renault Logan steering rack relieves the general steering system of backlash and knocking, which become the main causes and symptoms of a malfunction. In the process of debugging the steering rack, special keys and screwdrivers are used to quickly get to the desired nut, with which the part is adjusted.
Since the nut is under the hood, the car in the car service lifts up in order to open the steering column space for the master. Alternatively, a garage pit is used.
During the first adjustment, the nut can be closed with a special plug, which can be easily removed by prying with a screwdriver.
If the element is excessively "sticky", i.e. its move does not lend itself to an ordinary key, the craftsmen resort to the help of a hammer and a special lubricant that facilitates the movement of the nut along the thread.
Repair of the Logan steering rack without gur or with gur is carried out after removing the rack for its subsequent restoration.
List of further operations:
Removing the circlip from the distributor is the first step in the repair process.
Next, the spool plug is unscrewed, covering the spool nut, which is subsequently also unscrewed with a special tool.
The pressure adjusting nut is removed after.
Next, the clamp spring is removed, as well as the clamp itself.
The distributor hidden in the housing is removed by knocking it out.
Next, the oil seal is removed from the distributor, as well as the bearing ring, which breaks in most cases.
The locking bracket is removed from the rear support. When prying with a screwdriver, it flies out by itself.
Next comes the buttstock and stem.
When the Logan steering rack is completely disassembled, all its components are qualitatively cleaned of oil, dust, and possible wear products. Degreasing is done.
The surface of the rod must be polished on a lathe with fine sandpaper. The distributor shaft is also subjected to grinding.
The preparation of the components is over. The stem comb is thoroughly lubricated with grease before returning to its place. All seals are replaced first.
Checking the compression of the stuffing box is a mandatory step before returning the distributor. A special sliding sleeve is shifted along its shaft, which takes the place of the bearing. Install the new distributor seal in the same way. All elements are carefully lubricated with grease.
Next, the retaining ring is returned to its place.
The stem clamp is installed after. Its place is completely filled with lubricant for ease of movement.
Then a spring is installed, which is fixed with an adjusting nut.
The back support is equipped with a centering support, after which the stuffing box and the back support itself are shifted along the rod. The element is securely seated.
The locking bracket is returned to its place.
When the work is completed, the Logan steering rack is checked using a special machine, which helps to identify possible leaks, and also provides a guarantee for the restoration carried out.
Steering rack failure is an important issue among motorists. Many are interested in the Logan steering rack, the price of purchase and replacement, we are often asked “Logan rack with gur price”, they are less likely to look for “Logan steering rack without gur price”, someone is interested in how Renault Logan gur steering rack is repaired, some are worried about repairs steering column Logan. In any case, in order to delay the appearance of such issues, it is worth listening to the recommendations of the masters and owners of Renault Logan.
Here are some tips, highlighted from the personal experience of average drivers, that will help you protect the steering assembly from premature wear and breakage:
It is never necessary to turn the steering wheel all the way out - this will reduce the force applied to the rack, which will significantly reduce the risk of wear.
Tie rod anthers should be treated with extreme caution - their breakage or defect can lead to fogging of the rack mechanism, which causes the GU fluid to leak.
The steering rack needs to be warmed up in the cold season in the same way as the engine.
Self-checking the condition of the steering unit largely depends on the quality of the liquid poured into a special tank. It must be clean and transparent. With any kind of turbidity or the formation of foreign bodies, the fluid is replaced.
Despite the high strength of the described mechanism, one should be attentive to the issues of diagnosing the Logan steering rack, which is best done in a service station. In the process of self-inspection of the steering assembly, you can lose sight of many small details that, together, can quickly disable all elements of the steering rack or steering column.
This once again indicates the need for qualified assistance during the operation of the car, since this approach provides not only comfort, but also safety while driving.

The Renault Logan steering rack is a special mechanism that ensures the transfer of forces from the steering wheel to the rotary rods of each of the wheels. In other words, this is a device that causes the front wheels to scroll in the direction the steering wheel turns.
Despite the apparent reliability, the node fails from time to time, requires replacement and subsequent adjustment. How is Renault Logan steering rack repaired and adjusted? What nuances should be taken into account? Let's consider these points in more detail.
VIDEO
According to the manufacturer, the resource of the steering rack is 180-200 thousand kilometers. To avoid malfunctions, it is enough to inspect at least once every 6 months and, if necessary, to revise (repair) the unit.
There are many reasons for node failure. Here are just a few of them:
Poor quality of roads, which increases the load on the node.
Accumulation of dust and dirt in rubber seals with subsequent corrosion.
Reckless driving style.
Natural wear and tear and so on.
How to determine the malfunction of the Renault steering rack? Often, a simple inspection is enough to identify a defect, as well as attention to the vehicle while driving. The first signs that a repair or adjustment is indispensable in the future are the appearance of extraneous noise, an unusual suspension knock, an increase in wheel play or steering stiffness. In such a situation, the best solution is to contact the service station to find the problem, and later to repair the front suspension using a repair kit. In some cases, it may be necessary to replace a failed node.
According to statistics, in the Renault chassis, the “weakest link” is the bearings installed in the front hubs. At least motorists complain about other components - thrust bushings, which are damaged due to poor-quality road surfaces. We mentioned the first signs of a breakdown above (knocking, vibration and increased backlash when turning the steering wheel). Consider the malfunctions and features of Renault repair in more detail.
Breakdowns and troubleshooting methods:
Many masters go the simplest way and solve problems with the steering rack by pulling the adjusting plug.
But if you strongly pinch the worm-type gear, the teeth wear out, which can cause many troubles in the future. But in a garage, there are not so many other alternatives to repairing a Renault rail.
If a knock is heard during the rotation of the steering wheel, then its source, as a rule, is the rack of the steering system due to a loose fit to the gear. One of the elements of the mechanism is a thrust nut, thanks to which the distance between the gear and the steering rack is regulated. If you tighten it, then the problem is most often solved.
“The main thing when doing such work is to be careful and not overdo it. If the setting is incorrect, the risk of wear of the worm units and their failure increases.
To tighten a nut or repair a failed assembly, consider the design features of the car. There are two options here:
Renault Logan has power steering. Consider the situation - the engine is turned off, and when turning the steering rack knocks. Don't be in a hurry to make adjustments. On cars with power steering, a special nut is present, but it is not recommended to rotate it (as mentioned above).
Start the engine and wait at least ten seconds. The activity of extraneous noise during the rotation of the steering wheel is most often reduced. Experts assure that this is the normal work of the GUR.If this happens, do not touch the Renault steering rack nut and continue to operate the machine.
If the problem persists, then before stretching the nut, bend the “tin” washer. Thanks to this forethought, the machine remains under warranty. Please note that the washer is riveted around the perimeter of the nut and fits snugly against the crankcase bolts. In some cases, a repair kit may be required (for more serious work) or a simple fluid change in the hydraulic booster. The latter option is relevant if the working fluid has not changed for a long time, and its properties have deteriorated.
The principle of operation is to turn the nut to the right to reduce the gap. The work on adjusting the Renault rail is done as follows:
Put the car on the pit and raise the handbrake to securely fix the wheels.
Dismantle the crankcase with a ten key (you will have to twist three pairs of screws). You can't do it alone - take a partner with you.
The recess in which the nut is installed is tightly closed with a cork (made of plastic or rubber) - remove it. Please note that it is not always possible to see the nut itself - find it by touch.
After dismantling the cork, you have several ways. Use a "flexible" or L-shaped key. In the latter case, the length of the handle should be ten centimeters or more. Alternatively, buy a special key.
Lift the wheel on the left side with a jack to get to the nut and remove it.
“Some people make 100 * 100 mm recesses with an angle grinder before pulling the steering rack. This is a dangerous technique and it is better to abandon it.
Then proceed with the adjustment. For this:
Turn the nut to the right at a small angle (15-20 degrees).
Command your buddy to actively steer left and right.
If there is a knock, pull again.
After the knock disappears, do a control pull for another 10 degrees.
If you strictly follow the instructions, adjusting the Renault rail will not take much time. But keep in mind that if malfunctions are detected, it may be necessary to replace the faulty unit (here you can no longer do without a repair kit). If any points remain unclear, watch the training video.

Replacing the steering rack on Logan can be done in a garage, with minimal effort if someone helps you with this. In the video, you can clearly see how to change the Renault Logan rail without having much experience in car repair.
To dismantle the steering rack you will need:
jack up and hang out the front of the car;
drain the fluid from the hydraulic booster;
unscrew and remove the steering tips;
unscrew the cross of the steering column from the passenger compartment;
unscrew the muffler (do not forget to disconnect the lambda connector) so that it does not interfere with lowering the subframe;
unscrew the 4 subframe mounting bolts and the lower engine mount;
unscrew the power steering pipes from the Logan steering rack;
unscrew two more bolts securing the rail to the subframe; finally, it will be possible to remove it and install a new one.
Having installed the steering rack in place, it is unforgettable to fill in new power steering fluid and bleed the system from air.
If mechanics are installed, due to its simpler design, the steering rack can last longer. Since some of the breakdowns can be associated precisely with hydraulics. But these cars are in the minority. Renault produces the latest models only with amplifiers (both hydraulic and electric).However, there are also without amplifiers, including rarities, and cars with power steering removed.
The general design of the part is as follows:
The rotation of the front wheels is provided by rods with tips connected to retractable mechanisms.
From the steering wheel to the thrust, the force is transmitted through the gear and toothed bar.
The rack is pressed against the gear and the spring mechanism is eliminated from play.
The body of the Logan rail itself is made of lightweight and durable aluminum.
Bearings provide freedom of rotation, and limiters regulate the maximum degree of rotation.
Among the signs of failure of the control mechanism are:
knocking while driving a moving car;
difficult steering wheel travel in both or one direction;
a large backlash is felt;
in the presence of power steering - a hum, as well as leakage of the amplifier fluid.
Among the factors affecting the performance of the node, there are:
extreme temperatures. Frost has a particularly negative effect on the state of the rail. In order for the power steering fluid to warm up, before driving, you need to scroll the steering wheel in different directions.
Bad roads: many holes and potholes, deep ruts, dust.
Lack of power steering fluid and oil.
Deformations during impacts while driving or illiterate repairs.
Marriage or installation of a steering rack that is not suitable for the characteristics, as well as its elements.
Untimely maintenance, diagnostics and inspections.
General aging of the mechanism (depletion of a resource, after which replacement of parts is necessary).
The diagnostic procedure includes:
superficial inspection of the state of the mechanism (including the presence of a leak at the rail with power steering);
determination of the knocking area (the check is carried out in tandem with an assistant);
backlash angle check.
All these works are carried out without removing the rack from the car. If any problems are found, it is completely dismantled. An inspection is also carried out, and stands that simulate real loads are used for testing.
do not require major repairs;
are not caused at all by a breakdown of any element of the rail.
It is possible that you need to replace the anther or stuffing box, that is, your costs will be minimal. True, it is impossible to pull with their replacement, otherwise the repair will be longer, laborious and expensive, or even lead to the need to replace the assembly assembly.
There are also cases when replacement is not required, but generally repair, when the rail only needs to be adjusted. This procedure is performed without removing and disassembling the assembly, directly on the car, and can get rid of a slight play or knock. It does not take much time, but only if you have experience and conditions. To get to the adjusting nut, you need to open the steering column space. And the adjustment itself is associated with turning the steering wheel, that is, it is also carried out by the master in pairs.
Repair is quite possible if the condition of individual elements allows them to be replaced without installing a new rail assembly. The wizard performs the following operations. On the car, the tips, shaft, pallet, rack mountings to the body are disconnected. In a vice, the stopper, plug and nut of the spool, clamping springs and distributor are sequentially removed. The oil seal, bearing, retaining clip, butt plate and stem are removed.
Consumables are replaced (anthers, seals, bearing).
The steering rack is assembled and installed on the car in reverse order.
Adjustment and testing is underway.
The power steering fluid is replaced, with the slightest damage to the reservoir, it must be replaced.
The cost of a car with a rail without power steering is much lower than with it. This captivates those who are not very concerned about driving comfort. And it becomes not so convenient without hydraulics.
The process of replacing a steering rack without power steering is almost the same as the procedure for repairing a part without an amplifier. When changing, it is removed and dismantled in the same order. Disassembly, cleaning, grinding, lubrication are also carried out. Only the stages during the replacement are still somewhat smaller: thanks to the simplified design, they can only consist in finalizing the mechanism.
Taking into account the fact that the rake is about three times cheaper without power steering, some motorists have a question - is it possible to install it on a car that is designed for power steering? More often, this question arises among owners of used cars who do not want to invest heavily in repairs.
the line is closed for oil circulation;
a short belt is installed;
the steering column is being modified.
The dispute about what is better: with or without power steering, that is, cheaper or more convenient, has long flared up on the Internet between motorists. Masters are advised to pay attention to the presence of analogues - they allow you to save a lot without losing comfort. Although in any case, it is up to the driver to choose, and our specialists will do everything to return the car to better handling.
The main disadvantages of independent repairs, which hardly anyone can argue with, are:
waste of personal time;
search for the necessary spare parts and materials for work (not the fact that they are optimal in terms of price and characteristics);
lack of guarantees for the quality of repair or replacement of the unit (without experience, it is easy not to notice any minor problems).
